Abstract
The utility model relates to a dust collecting coal conveying corridor system. Dust collecting openings are arranged at the joint of a coal feeder outlet and a flow guide groove, at an inlet of a coal hopper of a breaking machine, at flow guide grooves of belts for receiving coal and at inlets of coal discharge hoppers of the belts of the system respectively, and are connected with bag-type dust removers through main pipes; and the bag-type dust removers are connected to a induced-draft fan. The system can not only collect coal dust, but also protect the environment of the coal conveying corridor of a boiler and the surroundings, and keep the equipment kinematic pair in the coal conveying corridor in cleaning state, so as to prolong the service life of the equipment and reduce the equipment maintenance workload.
Description
Technical field
The utility model relates to a kind of coal delivery of boiler gallery system.
Background technology
At present, the arrangement of domestic coal delivery of boiler system is: forklift is delivered to coal dropping port to feed coal and is sieved and enter feed coal ground hopper (being commonly called as melt pit) after removing bulk, feed coal in the hopper drops on the 1# belt through deflector chute by feeder, feed coal is carried through the 1# belt, arrive pulverizing building coal bunker by way of tramp iron separator, belt tightener, coal in the coal bunker separates through screening machine, coarse coal enters disintegrating machine, fritter and broken coal are then directly fallen on the 2# belt, and the coal after crusher in crushing removes the 2# belt again.Coal on the 2# belt enters the 3# belt equally behind devices such as tramp iron separator, belt tightener and flapper, the coal on the 3# belt is distributed to again specifies boiler to burn.The coal dust of blowing out in this process has not only caused the waste of material, and environment is caused severe contamination.The place of wafting and briming with coal dust has: (1) feeder is exported to the guiding gutter place; (2) broken building enters coal coal bunker place; (3) 2# belt coal breakage guiding gutter place; (4) the 3# belt enters coal coal bunker place; (5) the straight-through coal spout of 3# belt is to 3# belt guiding gutter place; (6) other belts meet the guiding gutter place of coal, the coal bunker import department of other belt coal breakages.
The utility model content
The purpose of this utility model provides a kind of defeated coal gallery system of gathering dust; this installs both recyclable coal dust; can protect coal delivery of boiler gallery and surrounding enviroment again, and make the interior equipment moving vice division chief of defeated coal gallery, to prolong equipment life, to reduce the plant maintenance workload in clean state.
The technical scheme that the utility model adopted is:
A kind of defeated coal gallery system of gathering dust, in feeder outlet and guiding gutter joint, broken building coal bunker import department, 2# belt meet the coal bunker import department of coal bunker import department, the 3# belt coal breakage of guiding gutter place, the 2# belt coal breakage of coal, guiding gutter place that the 3# belt connects coal, and other belts meet the guiding gutter place of coal, the excessive dirt pits such as coal bunker import department of other belt coal breakages are respectively established a suction port, suction port is connected with sack cleaner by female pipe, and sack cleaner is connected to air-introduced machine.
Be provided with butterfly valve between described suction port and female pipe.
The coal dust that sucks each suction port enters female pipe with air, and female pipe is connected to the air-introduced machine inlet by sack cleaner, and the air channel of cleaned air passes after the air-introduced machine outlet enters atmosphere.The collected coal dust of sack cleaner can pass through Pneumatic conveyer, delivers to boiler continuously, enters the burner hearth burning with boiler secondary air, also can concentrate and reclaim his usefulness.
Recyclable coal dust in the utility model can be protected coal delivery of boiler gallery and surrounding enviroment again, and the overlay film cloth bag of employing can guarantee also can successfully separate with cloth bag when the coal dust water content is big.Pulse backblowing is adopted in the cloth bag blowback, and employing compressed air is the blowback source of the gas.Deduster housing, cloth bag keel and suction port to the pipeline of sack cleaner adopts the ordinary carbon steel material to get final product.The wind speed of each suction port is by the butterfly valve opening adjustment that is connected with suction port.For avoiding by material and the fricative accumulation of static electricity of pipeline, and cause danger such as coal dust explosion, the utility model is provided with good earthing or grounding means.
Description of drawings
Fig. 1 is a structure chart of the present utility model;
Wherein: 1. hopper, 2. feeder, 3. deflector chute, 4.1# belt, 5. broken building coal bunker, 6. screening machine, 7. disintegrating machine, 8.2# belt, the coal bunker of 9.2# belt coal breakage, 10.3# belt, 11. butterfly valves, 12. electronic baffle plate three-way pipes, 13. sack cleaner, 14. air-introduced machine, 15. female pipes, 16. suction ports.
The specific embodiment
A kind of defeated coal gallery system of gathering dust, meet the coal bunker import department of coal bunker 9 import departments, 3# belt 10 coal breakages of guiding gutter 3 places, the 2# belt coal breakage of coal, guiding gutter place that the 3# belt connects coal at feeder 2 outlet and guiding gutter 3 joints, broken building coal bunker 5 import departments, 2# belt 8, and other belts meet the guiding gutter place of coal, the coal bunker import department of other belt coal breakages respectively establishes a suction port 16, suction port 16 is managed 15 by mother and is connected with sack cleaner 13, and sack cleaner 13 is connected to air-introduced machine 14.
Described suction port 16 and 15 of female pipes are provided with butterfly valve 11.
The coal dust that sucks each suction port 16 enters female pipe 15 with air, and female pipe 15 is connected to air-introduced machine 14 inlets by sack cleaner 13, and the air channel of cleaned air passes after air-introduced machine 14 outlets enters atmosphere.Sack cleaner 13 collected coal dusts can pass through Pneumatic conveyer, deliver to boiler continuously, enter the burner hearth burning with boiler secondary air, also can concentrate and reclaim his usefulness.
Claims (2)
1. defeated coal gallery system of can gathering dust, it is characterized in that, in feeder outlet and guiding gutter joint, broken building coal bunker import department, each belt meet the guiding gutter place of coal, the coal bunker import department of each belt coal breakage establishes a suction port respectively, suction port is connected with sack cleaner by female pipe, and sack cleaner is connected to air-introduced machine.
2. according to the described a kind of defeated coal gallery system of gathering dust of claim 1, it is characterized in that, be provided with butterfly valve between described suction port and female pipe.
